[PATCH 6/7] maint: make silent builds the default

The user still has full control over verbosity levels, both setting
their per-project defaults at configure time (or even in a config.site
file), as well as a per-run override. But these days, most projects
are defaulting to silent rules without user intervention.

* configure.ac (AM_SILENT_RULES): Add, to match what most projects
are doing these days.

(cherry picked from commit b4a08ecfd34e703bd846f1e85b4e2a94a34b16d9)
[For the cherry-pick, all we have to do is normalize the spelling
of the line - now that we require new-enough automake, it does not
have to be conditional]
